The blue light option is not available even after following instructions such as deleting the blue light in the registry app. Help!

N73 Flashing blue light

I'd just like to thank you for raising the question, at least, as it's let me know what the heck the light is for.

How you can have a phone with a flashing blue light on the front and not mention it in the manual is a little amazing (I mean, I just searched the PDF manual for the word "blue" and it's not there. It's not under the list of important signals at the front,
there's nothing pointing at it in the pictures of the phone...)

 

Blue Light Reduction cannot be turned off

My laptop is Thinkpad W530. The system is windows 10 home edition build 14393.693.
I set up my screen by using Blue Light Reduction (BLR). Now everyday after 9pm, the screen goes into blue light redution model. However, I want to revert it back to normal. The interesting thing comes that I cannot find way to. *SadNo BLR button in quick action. No BLR shows up in settings-display.

Here comes questions:
1) How could I get it before? I remember it bubble up before to let me set up.
2) How could I revert the system back to normal if I cannot do the same steps as instruction in my laptop as link below:

Blue Light Reduction - Turn On or Off in Windows 10

3) Is that I can only wait the system updated to like build 15007? Where I can download 15007?
